Xsyon Update Buffs and Increases Wildlife Population
Xsyons latest update aptly titled Repopulation makes a number of changes to the creatures of the world. The patch modifies the migration system to help maintain balance across the land and also repopulates once sparsely inhabited areas. Additionally, some of those creatures will become stronger with age, combat experience, and survival, so be careful not to bite off more than you can chew.
Read the patch notes for a full list of the latest changes.
